New Netflix crime series Dept. Q seems to have been a hit with both critics and viewers - with hopes that a second series could be on the way.
Based on a series of book by Danish writer Jussi Adler-Olsen, it sees Matthew Goode play police detective Carl Morck, who is put in charge of a cold case unit in Edinburgh.
Chloe Pirrie, Jamie Sives, Mark Bonnar, Leah Byrne, Kate Dickie, Shirley Henderson and Kelly Macdonald also star.
The series was filmed across Edinburgh and Scotland, and eagle-eyed viewers have been trying to work out where the real locations are.
Here are 17 of them.
5. The Calders
The disturbing opening scene was filmed in the Calders - a residential estate on the western outskirts of the city, near Edinburgh Airport. The action quickly moves from the modern to the traditional setting of the Old Town. | Google Maps
6. John o’Groats Ferry
The scenes on a ferry which prove pivotal to the plot were shot on the ferry that goes between John o’Groats and Orkney. | Contributed
7. Johnston Terrace
The exterior of police headquarters in Dept. Q - with the titular department in the basement - is actually a former job centre on the corner of Johnston Terrace and Castle Terrace. | Google Maps
8. Edinburgh International Climbing Arena
A key scene (no spoilers!) takes place in a climbing centre. This was shot at the Edinburgh International Climbing Arena which, despite the name, is located just outside the city in Ratho. | Google Maps
